Hi there!
To get an idea, graph the function using an application such as Desmos.
The range tells you what values of y the graph may be. Looking at the graph, we see that y can be a value of 3 or larger (look at the y-intercept, which is the vertical line, and find the lowest point in comparison to the vertical line if the graph has a minimum. If it has a maximum, do the opposite).
Means greater than or equal to.
Therefore, the answer is C, which means y is greater than or equal to 3.
Hope this helps!
The area of the two triangular faces is
triangle area = (10 cm)·(24 cm) = 240 cm²
The area of the rectangular faces is
(23 cm)·(24 cm + 10 cm + 26 cm) = 1380 cm²
The total area is the sum of these
240 cm² + 1380 cm² = 1620 cm²
A sample set contains every possible outcome.
The answer would be:
(R, 1), (R, 2), (R, 3), (R, 4), (R, 5), (R, 6), (B, 1), (B, 2), (B, 3), (B, 4), (B, 5), (B, 6)}
Answer:
For every 2 quarts of water, ¹/₂ cup of vinegar is used.
⇒ To find the amount of vinegar, divide the number of quarts by 4.
⇒ To find the number of quarts, multiply the amount of vinegar by 4.
4 qt water = 4 ÷ 4 = 1 cup vinegar
1¹/₂ cups vinegar = 1¹/₂ x 4 = 6 qt water
8 qt water = 8 ÷ 4 = 2 cup vinegar
Plot the points on the graph (see second attached image).
Draw a line through the points.
Find 3 along the x-axis and trace up to the line. Trace along to the y-axis.
Therefore, Gavin would need to use 12 quarts of water with 3 cups of vinegar.
